Providing multiple selection options in Search help

This document specifies how to include multiple select options for the given fields in the search help. For example below we can see that for material we have single selection possible.

So to convert it in the select option we need to follow certain steps.

We need to create a “Search Help Exit” in search help. Search help exit is a function module with the same interface like “F4IF_SHLP_EXIT_EXAMPLE”.

Double click in the search help exit name and paste the following code lines:

DATA:type_info LIKE dfies.

callcontrol-no_maxdisp =
'X'.

IF callcontrol-step EQ 'SELECT'.
callcontrol-step =
'DISP'.
ENDIF.

CHECK: callcontrol-step
EQ 'DISP'.

CALL FUNCTION 'TABCONTROL_VISIBLE'
EXPORTING
visible =
'F'
tab_id =
1.

SUBMIT zmat_search VIA SELECTION-SCREEN AND RETURN.
IMPORT record_tab TO record_tab FROM MEMORY ID 'REC1'.

READ TABLE shlp-fielddescr INDEX 1 INTO type_info.
type_info-leng =
18.
CLEAR type_info-offset .
MODIFY shlp-fielddescr INDEX 1 FROM type_info
TRANSPORTING leng offset.

callcontrol-step =
'RETURN'.

Create a executable program and paste code lines like this:

REPORT zmat_search.

TABLES: mara,makt.
TYPE-POOLS: slis.
DATA: gs_fcat
TYPE slis_fieldcat_alv ,
gt_fcat
TYPE STANDARD TABLE OF slis_fieldcat_alv ,

TYPE slis_layout_alv .

END OF gs_output,

LEAVE SCREEN.

ENDCASE.

ENDFORM.

Save and activate both Search help and Search help exit and run the search help.

Screen – 1

Press enter,

Screen – 2

Press Enter.

Screen - 3

Give the selection values and press F8. Output will show in ALV. Select any line and find the values in the corresponding selection box.

This search help can be attached to the standard search help say MATNR search help in MM01. BASIS will perform this action.
